Patent CA-2140854-A1 (CA)
Inventor: ONODERA AKIRA
IPC: C07D501/59
Filed: 1993-06-17
Abstract: Many antibiotics of cephalosporin series useful as drugs are known, and many of them are administered parenterally because of low oral absorbability.  Of the oral cephalosporin drugs used clinically, cephalexin and cefachlor show high oral absorbability, but have extremely inferior antibacterial activity against gram-negative bacteria to injectional cephalosporin drugs.    Oral cephalosporin drugs of which the oral absorbability is elevated as so-called prodrug have been recently developed.  These compounds have stronger anti-bacterial activity against gram-negative bacteria than cephalexin, etc., but remain the drawbacks of lowered antibacterial activity against gram-positive bacteria and the oral absorbability which is not so good.         The present invention relates to cephalosporin derivatives represented by the formula:                             (I) (wherein R1 and R3 are each a hydrogen atom or a lower alkyl group, and R2 is a hydrogen atom or an in vivo hydrolyzable group) having both potent antibacterial activity and high oral absorbability and non-toxic salts thereof, and the drugs containing the compounds of the present invention as an effective ingredient have not only potent antibacterial activity against various phathogenic bacteria including gram-positive and gram-negative bacteria, but also excellent oral absorbability with low toxicity, and therefore, they are useful as antibiotics for oral administration.

Title: Game ball with synthetic leather cover
Inventor: WALKER ALAN D
IPC: A63B37/00
Filed: 1995-03-07
Abstract: A softball has a high end synthetic leather stitched cover formed from a non-woven fiber mat impregnated with polyurethane. The softball, which can be formed to meet association specifications, has a cover to core weight ratio significantly less than 0.2 and typically in the range of 0.08 - 0.16, while meeting durability requirements. Because a greater weight concentration is in the core of the ball, the ball has improved playability characteristics over conventional balls having synthetic leather covers.

Patent CA-2161152-A1 (CA)
Inventor: SACH GARY M
IPC: H01H3/02
Filed: 1992-04-23
Abstract: A tactile  feedback  switch  actuator  (12)  for  an associated force-actuated switch (52) has a key cap (22) linked to a collapsible dome (34)  by an optical fiber (36), all of which are light-transmittable.  The actuator (12) is operated by manually applying an actuating force to the key cap (22) which exceeds the modulus of collapse of the dome (34).  In response, the dome (34) reversibly collapses  in  a  tactile  snapping  action  against  the underlying light-transmittable switch panel (54) having pressure-sensitive contacts (62a, 62b) embedded therein to change the operative state of the switch (52).  When the actuating force is withdrawn, the collapsible dome (34)  elastically returns to its uncollapsed condition, while  the  switch  (52)  remains  in  its  newly-actuated operative state.  The actuator (12) and associated switch (52)  are structurally integrated and aligned so that light-emitting   pixels    (60)    in   an underlying electroluminescent panel provide visual feedback of the operative state of the switch (52).
